Workshop for the timing belt in the Offenburg area

Hello, I have found a relatif inexpensive replacement for my capputen V70 TDI, the only one the previous owner has not taken it so accurately with the maintenance intervals, which were always made by the workshop in the village! The fact is that the dental worker is already 12 years old even if the car has not yet exceeded the mileage limit until the next revision (all 120 000 KM). As far as I remember, the change interval is at 8 years. I had once again called Volvo in Deuschland and France for a standart estimate. Teeth belts with pipapo (simmerrings, flywheels, corner rollers, etc….) In D. 1200,- € In F. nearly 2000,- € So if I want to double the car value I should do that. But maybe one of you knows a nice friend, in the area Offenburg/Kehl or radius 50 Km of one not the whole month salary of a middle-sized citizen makes up for 6 hours of work. Maybe someone can help me over PN/PM already thanks you.
